Corwin's Notes
=====
NGC 3508 = IC 2622 (which see) and is probably also = NGC 3505 (also which
see). WH called this "small" while his son saw it as "vL" -- WH is closer
to the truth. Both positions are good, so there is no doubt that both men
were looking at the same object.
Similarly, Swift's note "... looks like a D *" in his description makes it
clear that he, too, was looking at the same galaxy. In his case, however, the
position is off by a few arcminutes to the northeast.
-----
As noted above, re-reducing JH's observation of NGC 3505 (which see)
definitively shows that it is identical to NGC 3508. His description of the
galaxy in that observation also removes the size discrepancy.
Steve's Notes
=====
NGC 3508
18" (3/13/04): fairly faint, fairly small, round, 0.7' diameter, even surface brightness. A mag 13 star is attached on the NNE tip of the galaxy. At times the galaxy appears slightly elongated N-S, ~1.0'x0.7' and the DSS image confirms this impression. Observation made through thin clouds. This is a starburst and luminous infrared galaxy with an active nucleus.
